Said helical nm is at intervalsprovided all alon its lengthwith scra ers 3 to prevent the ormationof--a cake o? ness on the metallic web of the filter B, said Scrapers`3`being actuated by. compressed air. The Scrapers 3 are. verticallyposltioned and are mounted b y means of a stem 33 with excessivethickwhich they. are providedon a framework 34 mounted' on the end ofthe stem 35 of a piston 37 adapted to reciprocate inside of acylindrical ap 56 formed transversely in the helical rim v4 and in thewall of the cylinderl A, said piston stemA being guidedv 'through a holein a transversal partition 57 of said gag. Interposed between thatpartition and t e piston 37 is a spiral'spring 36, andthe iston 37 isprovided with a stop. 58. Be ind thepiston 37, there is a compressed airchamber `32 to which the air is admitted by a tube 32 inside of theheli- 32.
